Overview

On Gadi, users should submit jobs to a specific queue to run jobs on the corresponding type of node. For example, jobs need to run on GPUs have to be submitted to gpuvolta queue to get access to nodes with GPUs, while jobs requiring large amounts of memory may use the hugemem queue. If your job can run on the nodes in one of the normal queues, you should use those queues. The normal queues have more nodes available for your jobs, and this allows users and jobs that do require more specialised queues to get fair access to those queues.

Gadi queue structure also has two main levels of priority, express and normal, which is reflected in the queue names. Express queues (express and expressbw), are designed to support work needs rapid turnaround, but at a higher service unit charge.
